Used this before. It works well when others don't want to blend together.
Happy to be stocked up on this again.

Great product
Polyvance makes great products. These rods along with their steel mesh are still holding the floor together in my RZR after an A-arm ripped through it. 3 years strong.

The go to for old dash pad repair
This will melt into that old dash pad foam, and can be shaped immediately. It made restoring the pad a breeze.

great stuff
If you do any plastic welding then FiberFlex is the stuff to have around, because it is so versatile. You can patch up about anything with it and it really works good with the reinforcement materials, like mesh screening and such. It is a must have item to melt things back together.

Works well -- not as durable as I had hoped
Overall, this material works well. It was able to "stick" reliably to some hard plastic that I was trying to repair. Unfortunately, it wasn't as durable (hard? Tough? resistant to breaking?) as I had imagined it would be from reading the manufacturer's description (from Urethane Supply's website). The item that I repaired broke off at the original site from stress. Obviously, this wan't a fault of the product as the original item had broken from stress at the same site. I thought from the description that the product would be a lot tougher than the normal polypropylene or polyethylene I had tried to repair. It does adhere to those substances as advertised -- while it broke at the stress site, the fiber flex substance itself did not tear away from the host item.

Extremely Happy is all I can say.
Extremely Happy is all I can say. I have welded my lower bumper (fiber reinforced bumper) with these rods on my Prostar after a deer strike shattered it into many pieces. Low and behold, someone backed into us and craked the bumper a second time 2 weeks later. i was surprised to find that none of the welds cracked, but it cracked in all new places. I welded it up in all the new places, smoothed it all out, re-painted it again,.. all is good now.

The best product for plastic welding
Have not gotten product yet but I can say this product is some of the best product for welding if not most all plastic. Just bought 2 pounds of this from the main supplier, I use this all the time great strength in welding plastic. If you weld plastic this is a must have item , yes it’s expensive for a reason it’s the best out there .

excelente
Esta plástico para soldar ya lo había utilizado previamente para soldar kayaks recreativos de plástico, tanque de agua de embarcaciones e incluso un tanque de gasolina, debo admitir que es un buen producto sabiendolo aplicar bien.
